Nature: Season 31, Episode 2
Take an intimate look at the snowy owl, a bird made popular by Harry Potter's faithful companion, Hedwig.

鹦鹉，叫声喧闹，毛色绚丽，通常远离原产地。看似不起眼，但它们正在全世界范围内占据我们人类的城市。从澳大利亚悉尼到德国斯图加特，再到美国，几乎没有哪座大城市中没有鹦鹉的身影。然而，鹦鹉同时也是最濒临灭绝的鸟类之一。虽然在人类城市中得到了大量繁殖，在野外，许多鹦鹉品种都岌岌可危。在墨西哥，人们建立了繁殖中心，人类父母教授雏鸟们鸟生必备技能，然后放生到国家森林公园的丛林中。本片揭示了城市鹦鹉兴起、野生鹦鹉却衰败的原因，探索了鹦鹉复杂的社会结构，同时展示了人类为帮助鹦鹉重返自然作出的努力。
